Abstract (en)
[origin: EP0780552A1] A vehicle engine exhaust silencer comprises outer and inner tubular shells (1,2), the inner shell (2) enclosing an assembly of perforated tubes (4) and transverse baffles (5) forming a chicane. The assembly (4,5) and possibly also the inner shell (2) are made of enamelled steel sheet, the steel containing by weight in thousandths of percent 0-100 carbon, 0-500 manganese, 0-30 phosphorus, 0-40 sulphur, 0-60 aluminium, 0-200 titanium, 0-6- copper, and 0-15 nitrogen and the remainder of iron and residual impurities. The steel is hot-rolled to form a strip with a final rolling temperature above point Ar3, wound into a roll at above 600 (preferably above 750 or 700) degrees C and thereafter cold-rolled and annealed prior to enamelling.
